Taall whom t may concerne Be itA lnoWnthat Ir, NEWTON L. Sommes,- a'oitizen'l of the United States, residing: in the borough olilvlanliattan;7 city, oounty5-andy fState of New Yorl;`,ihave invented an Ianprove'ment in ElevatonSignal Systems, of which the followingf is a specification;

Ideretofore divers systems 'for signaling elevators have beenA adoptedy and used-as-for lfexmnple, elevator systems Vhave been ein-- ployed in which from. any given floor in a; building signal".v could be transmittedv to all? tile elevators in` the elevator' system inthat building, and uponl any` given elevatorv la approaching the floor from i whichv the 'originall signal-'Was given, indicaton lams Would be lighted; but in this-system, the indicator lamps` for several tiooivsf might be'` lighted Y byfeaehcarand:ifthediiierent cars hap' allthe-indicator lamps lwould 'be lighted, aindl consequently andi with vthis particular system,.there'fisfsuoh'-ndeniteness in nalsL as vto male'zit impossiblezor the person giving the originalfsignal, to tell which car in the system Will-stop in response 'to-his signal. So-far as In ain-aware, suoli'indeliniteness is alsoA they case inall the signaly systems which have heretofore been-devised, and the "object of my invention is to overL `come thisdiiculty anda provide anfelevator signal system,.in theJ use of which, ai signal may be given on any--floor of the building,

. 'Whic'hvvill indicate simultaneously'inf each. 1:-

Devicesareem ployed in each ofthe carsV for simultaneously extinguishing'the signal lamps Whichvhave beenli'ghted in giving any signal, and sigffrignal signal Was given, therebyrindicatw y ing to fthe person giving this original signal, `which car Will stop. I may also employ devices marking it possible for tbepartyl giv- 44' ing. the original signal, to know that his sig nal hasbeen transmitted to the. variousv cars.

The electrical connections between'. the' various parts of the apparatus hereinbefore described, in be explained in the description of the operation of the system, and this l will now proceed to do, by reference to Fig. 1.A

all probability can the better.

The line 48 -may indicate the positive lead and Cthe line 44S), the negative lead from any source of electricity. The lead 48 is connected to one terminal of both the push buttons 10y and 11. Now assumingthat a person is on the third iioor and wishes to take a car going down,-the push button 10 is pressed, making a circuit between theA contacts thereof. The second contact of this push button is connected by a wire 'A wire 52 is also-connected to the wire 50 and leads to one terminal of the cut in relay 18.A rlhe wire 53 is'connected to theother terminal of 'this cutfin relay 18 and to a wire 54 whichv is connected to thenegative lead 49. lt will 'therefore' be seen that by. pressing the y push button, the circuit will be closed through the cut-in relay 18, by the wires 50, 52, 53' and 54 and the circuit will also be. closed through the l,wires 55 and 56, connected across the terminals'of the lamp 14.l

By closing. the circuit through the cut-in 18, the armature 57 thereof is attracted andgmakescontact with 'the contact -annuncia'torl'amp corresponding to the .third "'lhe armature 57 coming into fioo'r in every car in the elevator system,-

'these circuits being as follows.:-

By Way of. the positive lead 48, the wire?.

19, the contact point 77,the wire 60,- the" armature 58, the.' armature 5.9 of the cut-out relay'4 57 of the cut-.in relay18, the contact point 51, 4the-vv1re50, `the wire 55, lamp. 14., 56, to thejnegative lead49, and also from the wire 50, through-the wire 61, lto

the wires 62, to the Contact points 34 'throug'hthe lamp'f23 in car No. 1, wire 64,

wire 65, wire 66, to the junction point '67 connected "to the' Wire 68, retrning to the neg-ative lead 49. Also by the wires' 69 and corresponding lamp in car- No. 2, through lthe Wires71-and 7 2, and the.

corresponding lamp in car 3, and through thev wires 731and.74 and the corresponding lamp in car 4. lt will therefore be Seen tliatthe signal has been given in each car,

reverse lthird floor who' Wishesto descend. Further that the. lighting of the lamp 14 Will indi- 'cate to the person giving the signal that the circuit has been'closedtothe lamps in the cars,.thereby indicating that this signal has been transmitted to eachgcar in the systeni.

lt is noted 'here thatlthe circuit is norinally opened at the armature 57 of the cutin relay 18 and normally closed at the armature 59 of the cut-out relay 19. It Will also bennderstood that the operator in one of. the cars,`-generally the one nearest the oor from which such al signal has been relceived,is to answer the signal.

In the present explanation, it Will be assu'med that car No. -1 is nearest the; third floor, and that theoperator of carNo. 1' 'answers this signal, Which he has received,

and in so doing, the operatorpresses the press button 26 of the annunciator lamp in his car corresponding to the third door.l thereby swinging the T-lever from its-normal positlon as shown in Figs. 2 and 3, to th. dot-ted linie position and in so doing,- the circuit to the lamp in car No.1correspond'- ing tothe third floor. down', is opened at the contact'plates 34, 35,-and another cir-' cuit is closed'vthrough the contact blades 39, 40, by the knife contact 38. This circuit Which is closed atthe contact blades 39 and 40, is as follows :fFroin the positive lead 48 through the'wire58, thecut-out relay 19, the Wire 75, through the lamp 17 ,Y the wire 76, thecontact point 40, contact point 39, the Wire 65, Wire 66, Wire 68, to the negative' It will therefore be .seen that in closing this circuit', the operator in car No. 1 has signaled back to the loor from which the original.- signal .Was given, indicating that this is the car Which Willstop there.

I At the' same 'time vby closing the circuit c Vsuitable mannerbet-Ween the shoe 78 and athrough the cut-in relay 19, the circuit hereinbefore vdescribed through the other annunciator lights in all the other cars of the system, has been opened by the armature 59 of the cut-out relay being attracted and breaking the circuit at the Contact point 77. This ofcourse indicates to the operator of the other cars that the 'signal from floor N o. 3 has been 'answered and therefore need not be given their attention.

The lamp 17 continues Lto burn until car A No. 1 has stopped at 'Hoor 3 and by the stopping of the car, or the opening of the door thereof,a cont-act may be made in any line 79, which vcloses a circuit through the annunciator relay in car No. 1 correspond-` ing to the third floor. .This circuit is through the shoe 78, Wire 79, to -the coil of `the up-annunicator of door No. 3, through the Wire 80 to the coil of the down-'annunciator in ca r No. 1 for floor' 3,- and through the Wire 81, the Wire 66, the Wire 68, -return ing to the negative lead 49. The closing of this' last named circuit resets the downannunciator for lioor 3 in car No. 1 Which has been operated, and in so doing opens the ckircuit to the-down signal lamp on floor 70.

Yo. 3. f

The circuits for operating the-u -signals are similar to those hereinbefore 'escribed for the down-signals- Takingas an illusl tration, the first car and a signal given from 75 thethird flo-or. It may be'. assumed that a person on this floor .desires to take the car going up. The push button 11 is then actuated,`closing the contacts thereof and making va circuit from the positive lead 48 through 'the `Wire 82 to the contact'point 83 and through the Wire'84 to the cut-in relay 20 from thisirelay, by the Wire 54 to the negative lead 49. This circuit being closed through the magnetfof the relay 20, energizes the same and causes the armature 85. thereof 'to be attracted to.contact with, the

vpoint 83.. This closes-a circuit through the up-annunciator lamps rfor oor 3 in every one of the cars. This circuit is as follows: 90 Froml the positive lead 48, through the Wire, 58, the Wire 86,' the armature 87, the cut-out relay 81, thecontact point 88, the Wire 89, the armature-85 of the cut-in relay 29, the contact 83, the Wire 82, the Wire 90, the Wire 91, through the contact points 92, 93, of the relay corresponding to the 11p-signal lamp` for iio'or 3 in car 1, (it being understood thatl the contact points 92, 93, correspond With the contact points 34, 3 5, as hereinbefore de- 10'() scribed) throughthe lamp 24, the Wire 65, Wire 66, Wire 68, to the negative lead.

It Will also be apparent that the circuit is closed through the up-'signal lamp for .the

lthird floor in each of the other cars:-

in car 2 by the Wires 94 and 70; in car v3 by the Wires 95 and 72, and in ear 4 by the- Wires 96 and 74. i 4 Noiv obviously the operator in each car 'has received the signal that someone on 111i floor 3 Wishes to take a car going up. Assuming for example, as was assumed before,-that car No. 1 is novv going up and is the nearest car to the third floor.. The' operator of c'arrNo. 1 then presses the but- '115 ton 26 of the annunciator for the 'up-signal lamp for floor 3, thereby swinging the arinature from the contact points 92, 93, break ing the circuit thereat, and at the saine time making a circuit between the Contact points 12b' 97 and 98. Making' the circuit at these contact points closes` the following circuit through the up-indicator lamp 16 on floor v3:--l1`ro1n'the `positive lead 48, Wire 58, wire f 86,4 through the cut-out relay 21, Wire 99, in 125 dicator lamp 16, Wire 100, contacts 97, 98, Wire 65, Wire 66, Wire 68, to the negative lead 49. Opening the annunciat-or lamp circuit at the contacts 92, 93, causes the lamp 24 in car 1 to go out and by closing the cir- 13o cuit through the Contact points 97, 98, the cut-out relay 2l is energized causing the armature 87 thereof to'brealzrtae annunciator light circuit at the contact point d82 thus extinguishing the annunciator lights in all the other cars. The-indicator lam 16 remains lighteduntil the car stops at t e thirdfloor to take on the passenger.
